I am not sure whether this is the exact forum to ask this question. If not please transfer it to another.


As we know the IoT is growing rapidly and millions of devices are invading our homes to our cars everyday. Most of these devices do interface with Web APIs. I know we can do this easily in hardware platform such as RaspberryPi or OrangePi.


But when it comes to Hardware with low memory, low storage and without any OS such as Arduino, how can we ensure the transport level security with any Web interface? I am doing a project now with NodeMCU and Arduino Ethernet and I need to ensure my communication with Web APIs are secured.


How can I achieve this ? can we use TLS certificates or are there any other methodology ?
